Zagg claims the graphene used in its Denali Snap case is “harder than a diamond, yet more elastic than rubber, and up to 200x stronger than steel”. Stronger still is Kevlar, which you might know is the material used to make bulletproof vests it’s also known as Aramid Fiber. Look for clear cases with anti-yellowing properties. However, cheaper clear TPU cases can turn yellow after a year or so due to ultraviolet rays. While not as thin as silicone, they aren’t very bulky and are more durable. Both are more resistant to scratches, shock, and abrasion than basic polycarbonate. Thermoplastic elastomers ( TPE) are more flexible and softer to the touch than Thermoplastic polyurethanes ( TPU), which are also flexible but more rigid. More rigid cases are usually built with polycarbonate. Silicone can attract dirt more easily and is less durable so you might have to change your case more often than products made with tougher materials.
It’s great at protecting a phone from abrasions and scratches but not for fall/drop protection. Materials: Thin, soft, and rubbery silicone is a popular phone case material that provides a comfortable grip while not adding any real bulk of the phone.
